INSECT-POWDER GUN.

EEPECIl-"ICATION forming part of Letters Patent No.337,943, dated March16,1886.

Application filed June 22, 1885. Serial No. 169,412. (No model.)

To all whom it may concern:

Be it known that we, CLARENCE A. FONER- DEN and HENRY BELL, citizens ofthe United States, residing at New York, in the county of New York andState of New York, have invented certain new and useful Improvements inInsect-Powder Guns; and we do declare the following to be afull, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

Our invention relates to guns or blowers for spraying powder, and hasfor its object the provision of a simple and efiective device by meansof which air is forced directly through the body or mass of powder, andcaused to throw the same in the form of sprayed dust or powder throughthe nozzle of the gun.

As heretofore constructed, guns for scattering powder have been formedwith hollow bulbs placed at the end of long tubes away from the body orbarrel of the gun. Our invention provides for placing the bulb orblowerimmediately at the end of said barrel, so that the whole deviceshall occupy but small space, and to guard against the easy escape orloss of the bulb the bottom of the convex plug or end is thick, and atube or stem extends to the interior of the barrel through this thickend, so as to be held securely thereby and keep the bulb in place.

The accompanying drawingsillustrate what we consider the best means forcarrying the invent-ion into practice.

Figure 1 is a side elevation of the device complete, showing the form inwhich the nozzle is removable, and the rear plug integral with thecylinder. Fig. 2 is a central longitudinal section of the same. Fig. 3is a central longitudinal section of the form in which the rear plug isremovable, and the nozzle fixed or integral with cylinder or barrel.

Similar letters of reference indicate corresponding parts in all thefigures where they occur.

A is the cylinder or barrel, formed of wood or other suitable material.

B is the nozzle or stopper, which is removable from the barrel orcylinder in the form shown in Figs. 1 and 2, or integral therewith, asshown in Fig. 3. In either case it has the conical or cup -shaped cavityB, and the opening or aperture 1), extending from the apex of the cavityto the top of the nozzle, and the sieve orstrainer O, placed over theentrance to the cavity B.

In the form shown in Figs. 1 and 2 a rim or flange, B of aslightly-tapering form, is secured to the lower end of the nozzle andenters the head of the barrel, its tapering form rendering it tight andsecure. Ihe opposite or lower end of the barrel is closed by a plug orhead, D, which may be integral with the barrel, as shown in Figs. 1 and2, or separate and removable therefrom, as shown in Fig. 3. It has ineither form a cup-shaped or con cave exterior, D, into which fits theair bulb or forcer E, which has an open stopper, 6, with an enlargedhead, (2, for holding it securely in the bulb, said stopper or neck 6passing through an opening in the plug or head D. WVhen the bulb iscompressed, the air will be forced through the neck 6 and through thepowder in the cylinder or barrel, throwing said powder out through thenozzle in sprayed or scattered particles.

In the form of plug or head shown in Fig.

3, as already stated, the head is removable and the powder is poured orintroduced into the barrel through it, while in the form shown in 85Figs. 1 and 2, where the nozzle is removable, the powder is introducedthrough that end of the barrel. In the removable form of plug or head apacking may be provided around it to insure a close tight fit, as shownat D 0 in Rig. 3. A second sieve or strainer, C, placed directly overthe mouth of the stop per 6, as shown in Fig. 2, or at a little distancefrom it, as shown in Fig. 3, is employed to prevent the powder fromfalling into the 5 bulb.

\Vhat we desire to claim and secure by Letters Patent is In aninsect-powder gun, the combination, with the barrel A and nozzle B b, ofthe con- 10o cave end plug or head having the thick bottom described,with a central opening therein, and the hollow bulb E, having the tubeor neck 0, for insertion through the hole in 5 the thick bottom, and theflange or securing-ring e, for holding the neck in the bulb, as setforth.

In testimony whereof we aflix our signatures in presence of twowitnesses.
